PHI S-92 Oral; My Previous Experiences (1 of 3) Flashcards
In regards to HAZMAT, how are PHI aircraft classified?
Passenger and Cargo Aircraft; except for a few customer agreements. IAW PHI OpSpec Para. A003 and FAA LOA.
What is the immediate action if you have a loss of tail rotor thrust?
Enter autorotation by lowering the collective
If you receive unexpected HAZMAT, what must you do as the pilot?
Refer to, and complete the HAZMAT acceptance checklist/acceptance guide to ensure the paperwork, quantity limits, placards, and storage are all correct. Mark “Accepted by PHI” on the HAZMAT sheet, then complete and sign the pilot notification form. File this paperwork with your manifests at the end of the day.
What do the quantity limits in column 9a and 9b of the HAZMAT acceptance guide refer to?
The quantity limit is per package, unless specifically noted as “gross”. If needed, suggest shipper make smaller packages.
If an SIC has only completed 5 approaches within the preceding 6 calendar months, is he/she grounded from flight?
No. They are only restricted from flying IFR with passengers. Based on a rolling 66-HIT.
UNLESS, a 135.297 was completed within the preceding 6-months. The 135.297 supersedes 66-HIT.
FAR 61.57, 135.297
What is a procedure that PHI has implemented to reduce the risk of dynamic rollover.
After landing, the pilot flying will reduce the collective to the full down position. The pilot not flying will confirm the collective is full down prior to initiating taxi. When taxiing, maintain a level aircraft attitude and ensure the aircraft is properly slowed prior to entering a turn. Also, adhere to the ground wind azimuth chart restrictions. (GOM Air Taxi [arrival])
What are the factors associated with dynamic rollover?
Rotorcraft Flying Handbook
A pivot point, rolling/lateral motion, and exceeding the critical angle.
How can you reduce the risk of dynamic rollover during taxiing turns?
Use the cyclic to maintain a level aircraft attitude, slow prior to entering a turn, and reduce power by lowering the collective if necessary.
What are the conditions conducive to loss of tail rotor effectiveness?
Rotorcraft Flying Handbook and Advanced Aerodynamics Textbook
Hovering with a left quartering headwind, left crosswind, or tail wind.
LTE Conditions: Think Mirror images!
Weather Vaning (10-2)
Increased AOA (1-5; worst at 3)
Weather Cocking (4-8)
T/R Vortex Ring State (7-11; worst at 9)
M/R Vortices interference (1030-1130) *Req’s the T/R to be level or below MR center of mass.
If you are making an approach at low airspeed, and your rate of descent increases as you apply power, what could be occurring?
Settling with Power
PHI’s Default: 40kts or less AND 800fpm or more
(M/R Vortex Ring State; Rate of descent is near rate of down wash and lift is lost)
Are items found on the status report mandatory?
No, only items found on the due list are mandatory. updated every 14-days.
What would be the corrective action to recover from settling with power (MR-VRS)?
Forward or lateral cyclic to regain airspeed and ‘clean’ air; lower the collective if possible to reduce vortices (reduce power).
What type of thunderstorms are typically associated with fast moving cold fronts?
Squall Lines
How many emergency exits are located in the S-92?
S-92 RFM, PTM
3 Type III emergency exits, 1 Type IV (upper air stair door), as well as 10 jettisonable passenger windows and 2 pilot windows.
Where can a pilot find information specific to IFR conditions?
Airmet S (for Storms)
Where can a pilot find information specific to turbulence?
Airmet T (for turbulence)
Where can a pilot find information specific to icing?
Airmet Z (for freeZing)
What is necessary for icing to form?
Visible moisture and the collecting surface must be at or below freezing. Suitable conditions exist when OAT in 4*C or less.
When do the prime pumps supply fuel to the engines?
S-92 RFM, PTM
Only, during a start with the fuel selectors in direct.
During X-feed starts valves close that prevent prime pumps from supplying fuel and ONLY the engine driven fuel boost pump provides fuel via suction.
What is a TAA?
AIM 5-4-5 d
A terminal arrival area is a designated area on an RNAV approach plate that advises the pilot of the correct altitude and procedure turn applicability for that sector. If cleared for that approach the pilot shall adhere to what is published in the TAA.
What does a cruise clearance authorize you to do?
A cruise clearance provides a block altitude between the clearance altitude and the MEA, and clears you for the approach and Missed procedures. (Note: If you call “Leaving” your cruise altitude, you can NOT return to it without ATC approval.)
What are the requirements for a visual approach clearance?
AIM 5-4-3
You must have 1000’ ceilings and 3SM visibility at the airfield.
The landing area and/or the preceding aircraft in sight.
Even on an IFR flight plan and must remain clear of clouds.
What is the transient dual engine torque limit?
s-92 RFM, PTM
101% - 120% for 10 seconds
What is the 30 second OEI TGT limit?
S-92 RFM, PTM
1049 degrees Celsius
During an engine restart with the air source switch in the ENG position, what supplies bleed air to the engine starter?
S-92 RFM, PTM
Either the APU or the opposite engine will supply bleed air, whichever is stronger.
During takeoff, the TGT gauge turns yellow. Have you exceeded a limit?
No. This is a precautionary range; No limit has been exceeded. Continue flight.
What is the appropriate procedure if you shut down the engine prior to a 2 minute cool down?
S-92 RFM, PTM
Motor the engine for 1 minute and until TGT is below 150 degrees Celsius, start the engine within 5 minutes and operate the engine at idle for 2 minutes, then perform shutdown. If this procedure is not performed, do not restart the engine for 4 hours.
In regards to fire protection, to which engine is the APU compartment connected?
S-92 RFM, PTM
The #2 engine
What occurs when the FIRE ARM button is pushed?
S-92 RFM, PTM
The fuel to that engine is shut off (via the fuel selector valve), and the respective main and reserve fire bottles are armed for the appropriate engine compartment.
What is the minimum visibility for departing KPTN if you are crew qualified and the approach lights are out of service?
Adequate visibility reference all runways, 1/4 SM or 1200 RVR if reported
How many oil pumps are located in the main gearbox?
S-92 RFM, PTM
2; Both pull from the same sump line and feed the same pressure line.
What type of rotor system is the S92 main rotor head?
S-92 RFM, PTM
Fully articulated rotor head
What is the minimum visibility for departing KPTN if you are crew qualified and the approach lights are out of service?
Adequate visibility reference all runways, 1/4sm or 1200 RVR if reported. If crew is not qualified, STD=1/2sm
What causes the rotor brake light to illuminate?
S-92 RFM, PTM
a. On the ground: when the PSI is greater than 8 +/- 2 PSI, OR one or more pucks are engaged
b. In flight: when the PSI is 8 +/- 2 PSI, AND one or more pucks are engaged
What are the different types of flight control mixing in the S92?
S-92 RFM, PTM
Collective to pitch
Collective to roll
Collective to yaw
Yaw to pitch
If you have a TR QUAD caution light, what has happened?
S-92 RFM, PTM
At least one of the tail rotor cables have broken.
What happens if you have a dual tail rotor cable failure?
S-92 RFM, PTM
The helicopter will not respond to pedal inputs with yaw (the nose will pitch up and down slightly due to coupling), and the tail rotor centering spring will set a tail rotor thrust setting that corresponds to trimmed flight at approximately 30 KIAS and 150 KIAS.
What type of landing would you accomplish with a TR QUAD caution light?
A running or roll on landing
Where does the AP computer receive its flight information inputs?
S-92 RFM, PTM
AHRS, ADC, accelerometers, radar altimeter, navigation radios, FMS, rotor brake, and the FADECs.
How do the AP computers monitor flight control position?
S-92 RFM, PTM
Through the use of rotary variable differential transducer (RVDT)
Do trim actuators move the flight controls?
S-92 RFM, PTM
Yes
Outer Loop. Trim actuators have 100% authority (stop to stop) at a rate of 10% per second.
What is the normal hydraulic pressure range of the 2 main systems?
S-92 RFM, PTM
3500 PSI - 4200 PSI
700 PSID
